Has anyone integrated Mailman3 with Spamassassin?

What I'd like is a way for emails that I click 'discard' on in Postorius, to be submitted to the spamassassin Bayes classifier to make it more likely similar ones will be rejected in future at SMTP conversation time.

I've not heard that anyone has done this. If there's a way to direct email into the classifier, then you can tell Mailman to send discarded emails to some email address, I believe. But I don't know anything about how that classifier is trained. You're likely to get better answers on Spamassassin channels.

To make it one-click would require code changes in both Mailman and Postorius. Not terribly hard as such, but would require some thought as we probably wouldn't want it to be Spamassassin-specific (I think Mark uses SpamBayes on some of his lists, for example, and I suppose rspamd also knows about classifier training).
